1'0 all Lu/1.0711, it 'nwry concern/.-

Be it known that I, Lno BERGMANN, a citizen of the United States,residing at 281 Jelliff avenue, Newark, Essex county, New Jersey, haveinvented certain new and useful Improvements in Punching-Bag Platforms,of which the following is a clear, full, and exact description.

My invention relates to punching-bag platforms or frames, and has for anobject to provide such a device of simple and inexpensive constructionwhich will overcome one of the main difficulties encountered instructures of this character, namely, jarring of the support to whichsame are attached. To this end I mount a yieldable receiver for the bagwhen punched or swung.

A further object of my invention is to provide a light one-piecereceiver, that is, one in which there are no joints to come loose.

To these ends my invention comprises the novel features of improvementand combination and arrangement of parts which will be hereinafterdescribed and finally claimed.

Reference is to be had. tothe accompanying drawing, forming part of thisspecification, wherein Figure 1 is a side elevation of a punchingbagframe or platform embodying my improvements; Fig. 2 is a plan viewthereof, the braces of the frame being broken away Fig. 3 is a detailperspective view of the upper end of the frame braces; Fig. 4 is adetail perspective view of the lower end of the braces, showing themortise or recess therein for grasping the arms of the frame proper;Fig. 5 is a side elevation of a modified form of i a punching-bag framehaving angular cross-braces; and Fig. 6 is a plan' view thereof, theside braces being broken away.

Like reference characters are intended to indicate corresponding partsin the several views.

Referring to the drawing, the numeral 1 indicates a wall or othersuitable support to which is attached, in any desired manner, a frame 2,which is composed of a transverse .bar 3, from which project outwardlyextending arms 4, 4. A cross-bar 4 is provided, from which apunching-bag 5 is hung, by a cord 6. For better support of the frame 2,I provide braces 7, 7, which enter, at their upper ends, a cross-bar 8(Fig. 3), which crossbar contacts the support land may be suitablysecured thoreto, the edge of the cross ed to pass through the braces7,7, at 14, and

bymeans of nuts 15 are secured in place. Upon the bottom of theframe-members 4 and 4, I yieldably mount a ring or hoop 16, p

the same being preferably made of a solid single piece of wood orsimilar material. The means of connection between said ring and saidframe are flat springs 17, 17, which are secured to the frame-members bybolts or screws 18, 18, at one end of said springs, and the ring 16 isattached to the said springs by means of the bolts or screws 19. It willbe noticed that the outer ends of said springs are free. This givesgreater resiliency thereto, whereby, when the bag is violently forcedagainst the ring 16, the same will slightly yield and rebound, thustaking up a great deal of the jar usually produced. The springs also actto cause the punching-bag to rebound more quickly than would be the caseif said ring were rigidly mounted.

In the modified form shown in Figs. 5 and 6, the outwardly extendingarms 4, 4 are braced by the angular braces 20, 20, at the point ofintersection 21 of which the cord 6 is attached. The springs 17, 17 arein this instance attached to the extremities of the angular braces 20,20. Said braces may be set into the arms 4, 4 as shown, and the usualmortise connections at the point 21 can be used. This mode of bracingmakes a very strong construction, which is less liable to give when thebag 5 is in motion, thereby getting better results from the springs 17.

Having now described my invention, what I claim and desire to secure byLetters Patent is:

1. A punching-bag platform, comprising two horizontally disposedparallel frames and springs interposed therebetween, substantially asdescribed.

2. A punching-bag platform, comprising a frame, means for attaching thesame to a support, flat springs secured at their ends to said frame, anda receiver carried by said springs.

3. A punching-bag platform adapted for attachment to a support,comprising a horizontally disposed frame, a brace detachably the latter,and means for attaching the plat- 10 secured to said frame and adaptedto contact form to a support.

said support, and a receiver supported by Signed at Terre Haute,Ind.,tl1is 11th day springs upon said frame, substantially as deof July,1906. scribed.
